GB_ElementList
GB had arrays of pointers to objects. As these objects no longer exist, code using element arrays should likely be re-written to be more efficient. The GA version of element lists return by value (not by reference).
// GB Code
GEO_PointList &pnts = gdp->points();
==>
// GA Code
GEO_PointList pnts = gdp->points();

But there is no GEO_PointList.. I check it existed 13.0 not 15.0
I traverse 13.0 HDK Documents related GEO_PointList.. It's so difficult to find out the replacements.

I search for Major Changes and HDK Forums, Documents. I cannot find.
I want use points() function.. OTL
